In this type of transport, a source of pressurized air is typically used with a maximum differential of 1 atm. Oil-free rotary lobe blowers introduce atmospheric air into a transport pipeline. The product to be transported is introduced onto the pipeline through rotary valves, which seal the pipeline but allow entry of the product. The product dissolves into the air stream, enabling its movement from the point of origin to the destination point, typically at atmospheric pressure.
